And get 'drowned' due to weight of the water above them?

The pressure is a constant in all directions around the fish. Inside the fish, he has organs to balance the osmotic pressure, and salt content, etc.
He is passing water through his body that is the same pressure as the water outside. so..no problems.
Similarly, a scuba diver breathes pressurized air as he descends.
UP TO A POINT that is.
Of course there are fish more suited to very deep conditions. Bigger eyes to emit more light.
Less colors, more red colors, to be less noticed by predators in the dark.
Less dependency on "bones" for structural support. Invertebrates pump the high pressure water into their bodies for support.
YOU feel the weight of a load on your shoulders... but you don't feel the weight of one mile of air above you, do you?

Do they feel the weight? YES they do. Do they get drowned due to it? NO they dont. Why? Do u realize that you have a few thousand cubics of air supported on your head and sholders? Thats because it has been bearing us down all our life and also because our body organs have developed to equalize the pressure of the air surrounding us. If you were to growup in vaccum and were brought in to earth's atmoshphere, you would be squashed by the air pressure.
Same for the fish, all fishes are adjusted to the pressure surrounding them. Push a surface fish deep enough into water and it will drown.

sturdy assertion Ha ha. properly a actual fish may be lifeless, it incredibly is authentic. through fact the fish is out of the water and he's not the place he could be, in the placement he belongs. it incredibly is like putting an athlete in a woman's knitting circle. He may be a fish out of water.

not really.
the reason is that the amount of pressure acting from the top of the fish is some what equal to that from the bottom. the actual pressure is that which is equal to
(thickness of the fish) * (density of water) * (acceleration due to gravity)
the high pressure is due to the high density not directly due to the column (the high density is an effect of water column height).

Their bodies are adjusted so they don't get crushed at great depths- they're in equilibrium with their surroundings.
If you pull a fish up really fast from great depths, you can screw up this equilibrium and make the fish "invert"--a big change in pressure can do gross things to them.

WEIGHT OF WATER DISPLACED BY THE FISH IS EQUAL TO THE BOANCY(UPWARD THRUST) SO IT BALANCES WITH THE WATER SO IT DOEST HAVE WEIGHT OF THE WATER.

no like us. we donot feel the weight of the air which is around us

NO.its their habitat
